In 'Thor,' that was my own hair. I grew it out. But I have naturally curly, blonde hair, so I'll never look like that. By the time I got to 'The Avengers,' I had come off two other films, which required me to have it very short. So I dyed it again and it was long enough to use a part of my hairline.

I was informed yesterday that there's a Twitter account for my laugh. Very hard to get used to things like that. Pretty amazing.

The character, as written on the page, is just a blueprint for a human being.

With any role, you're extending yourself and acting out things that never happened to you.

The thing about running is, if I run in the morning before work, I feel like I'm ahead of the day. Whatever work I've done in terms of preparation or research or thinking about the scene or the character, it all kind of crystallizes in that moment in the morning. And sometimes I have the best ideas then.

I had huge fun with Chris Evans, as Captain America, because super-soldier though he may be, he's still a man, up against a God who in his own mind is infinitely superior. Then, in the ring with The Hulk, we've got this silver tongued, lightening quick mind up against the embodiment of rage..Loki has this mercurial, transformative ability, not just physically but intellectually, so not all the fights are purely physical. Mind games? Maybe.

I think a healthy connection with the natural world actually makes us more human.
